Abstract
Treatment of severe lupus nephritis (LN) has been controversial, and according to recent guidelines and recommendations, cyclophosphamide still remains a first-line therapy. Herein, we present the case of a 37-year-old female patient who developed rapidly progressive glomerulonephritis, which was histologically diagnosed as class IV + V LN, with a large number of cellular to fibrocellular crescents (62 % of glomeruli). Although the patient was considered to have the most severe form of LN, complete remission was achieved within 6 months by multi-target therapy using tacrolimus and mycophenolate mofetil combined with methylprednisolone pulse therapy. Our experience suggests that multi-target therapy could be a potential treatment option for patients with severe crescentic LN.
